I would not worry too much Paul as your car may of been left standard with no major work being done prior to you buying it unlike Mr T's.
You can do a few quick checks yourself with string and four axles stands. Basically you will measure the difference from leading to trailing edge of the wheel rim, remember you need to measure to the vehicle center line and not to the opposite wheel as i have seen mentioned else where on the net.
Here's a good guide

I also bought one of these
http://www.ebay.co.uk/itm/Gunson-770...4AAOSwjVVVg8yO to check and set castor and camber angles which you do before setting the tracking. Check this out
https://www.youtube.com/watch?v=Ew87fLr6Omw that shows how to make an edge that you can then attach a castor camber tool to to give a greater accuracy if you wish, the rear camber is adjust with a spacer block under the rear leaf spring and the front camber by adding or removing shims between the wishbone and chassis, once again there is plenty of help guides on this subject.
Good luck matey and enjoy the rest of the holiday, those books look to be very interesting reading.
